Application filed. March 7, 1925. Serial No. 13,789.

This invention relates generally to life saving .belts land aims toimprove'upon'a ystruc'zture'such as is shown in my pending in thewater.l l

With' the foregoing and numerous other objects in View as will appear asthe description proceeds, the inventionA residesV in certain novelfeatures ofconstruction, and in lili the combination and arrangement ofarts as will be hereinafter more fully descri led and claimed. F ln thedrawing- I Figurel 1- ijsa fragmentary elevation of a lite saving beltwith my improved structure mounted thereon.

Fig.; 2 is an elevation'of the container and.

v lhg. .3 i's al 'longitudinal section therethrough.. l Y

Referring to the drawing in detail, it will be seen that 1 designates alite preserver of the inatable type which may be constructed as shown inmy above identified co-pending application, or of anyfother 4suitablestructure.

- j "lihis'indatable member 1 is normally deflated and has extendingtherefrom a flexible in llating tube2 which also-may be of any de siredstructure. 'A pair of flaps 3 are sewed onto the member -1 and haveapertures tor receiving lacing i so that a container 5 may be mounted,therein.V Any other. suitable means may be used tor mounting this conitainer.

My invention lies particularly in thecontainer 5 and the elements aboutto be described. rllhis container 5 is provided with a milled surface 6oran otherwise roughened portionon 'itsv exterior surface so as to beeld against slippin in the 'path3. The container 6- isprovi ed with aninternally vided in the bottle.

. tion thereof.

\\ber threaded in t threaded open end 7 and is adapted to receive abottle 8 containing highly compressed airr' A closure 9 of suitablestructure lis pro- A rubber gasket 10 is disposed about the endet thebottle 8 and is held inplace by a bushing 11 rotatably engaged in asleeve 12. This sleeve 12 is both externally and internally' threadedso. that it may be engaged in the threaded end 7 of the container 5. Amember 13 is threaded into the sleeve-12 and is provided with alongitudinally extending bore 14. terminating'at its outer end in avalve seat for receiving a check' valve 15' which is held in place by aspring 16. p

.. A cutter'l? is provided on the inner end of the member 13 and has abore extending therethrough 'coincident with the bore 14;.

.The tube 2 is engaged with the vouter .end

ol the member A13.

By threading the member 13 into the sleeve 12 the piercing of thecutters 17 may be brought into engagement with the clo- .sure 9 of thebottle 8 for cutting a hole therein. A`When a hole is cut into theclosure 9,

the liquid air is tree to expandv and will rush 'through the bore llhandthrough the tube 2 for indating the member 1 without any further e'orton the part oit the person wearingthe life preserver.

inasmuch as'the construction and operation ot the invention will now beclearly understood w-ithout'a more detailed descriplit is desired,however, to point out that numerous changes in the details ofconstruction, in the materials, and in the combination and arrangementof parts maybe eparting from the spirity resorted to without or scope ofthe inveniton as hereinafter claimed or sacrificing any of itsadvantages.

'Having thusy described my invention, what l claim as new is 1.y As anew article of manufacture, a tilling device for the tubes ot litepreservers and the like including a container in the4 container forholdin .highl com'- pressed air, a sleeve threade into t e container torholding the .bottle therein, a meme'sleeve and provided with alongitudinally extending bore, a cutter extending `from the inner endofthe member and provided with abore coincident with the tirstmentionedbore whereby the member eoY a bottle lil@ may be threaded into thecontainer lfor en-v gaging the cutter'with the bottle so as to piercethe same.

2. As a new article of manufacture, a filling device for the tubes oflife preservers and the like including a container, a bottle in thecontainer for holding highly compressed air, a sleeve threaded into thecontainer for holding the bottle therein, a member threaded in thesleeve and provided .with a longitudinally extending bore, a cutterextending from the inner end of the memher and provided With a borecoincident with -the first mentioned bore whereby the. member may bethreaded int-o the container for engaging. the cutter With the bottle soas to pierce the same, and a check valve in the -memher for allowing theflow of the air from the bottle but prevent-ing the flow thereof to-vward the bottle.

In testimony whereof I ahx my signnture.

RALPH LOUIS SCHROEDER.'
